I mean, I know a lot of people don't like doing it anymore but calling and asking has a fairly decent chance of working if online gives no details.

Personally I'm unsure how a bank could even force NFC to go through a specific provider, mine has always just issued virtual card numbers whenever I enrolled, And if the bank itself didn't support the provider automatically, I always called the bank to manually approve getting the virtual number. it's a little confusing to me that your bank even blocks the ability to in the first place. I would have thought you would have been able to use any mobile wallet that works on Graphene OS. Being said those are limited last I knew

edit: rereading it. I see what you mean. You mean through your bank's app as a native solution. Yeah, you're just gonna have to call the banks for that one. I would assume that customer service would definitely know whether or not it's through Google Pay or through their own system.
